Two Red Tail Hawks, Oklahoma and Texas.

I need to get a better telescopic lens. These are two different Red Tail Hawks that look almost identical. The top one was in Oklahoma, and the second one was in Texas while quail hunting. They try to get the wounded quail. I have seen them attack quails when the dogs flush them, and also after they have been shot I have seen them attempt to "steal" the quail before the dogs get them. I am going to try to capture one with better details, closer. These were pretty far up in the sky.
